METHOD. OF MAKING COMPOSITEWALLS.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed November 19, 1906. SerialNo. 344,088.

To all whom it may concern:

Be it known that I, ELI MARTIN, a citizen of the United States, residing at Detroit, in

have invented new and useful Improvements in Method of Making Composite Walls, of which the following is a specification.

This invention relates to an improved composite wall and method of making the same. The object of the invention is to produce a fireproof composite wall which is built or molded at the place where it is'to remain, the

plied to a wooden frame to cover and protect the same.

A further object of the invention is to form such a wall with an imitation of rock, brick, or other pattern face. Y

'T he invention further provides a continuous air-space extending from the top of the wall to the bottom, which will serveto exclude heat, cold, and dampness.

A further object of the invention is to prowall in a simple and cheap manner capable of being practiced by unskilled persons and requiring no special apparatus for its performance.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view, partly broken away, of the invention. Fig. 2 is a horizontal sectional view illustrating the method of molding the wall. Fi 3 is a similar view of the completed wafi, the mold backing and facing having been removed.

In constructing the wall the frame is first made of the usual sills and corner-posts and cross-beams, as in constructing a frame house, together with studding, as indicated at 6, extending vertically in the .usual manner and set, if desired, closer-together than ordinary. To the outer side of this studding is secured, by nailing or otherwise, wire fabl ric, expanded metal, or other lathing, as indicated at 7 A series of nails are then driven part way into the studding with their heads or outer ends left projecting an inch or two, as indicated at 8. The distance may be varied according to the thickness of wall desired. Then a facing mold-section 9, of sheet metal or the like, is tacked or otherwise secured in place at the front, resting against the heads of the nails or pins 8. It may be conveniently held in place by a few nails driven through the same into the studding. The sheet is preferably made of thin metal, such as tin, having the design of the wall impressed on its inner face. Thus it may be imitation of rock face, brick, stone, or any other design. Boards or planks 10 are then set up endwise at the back between the studding 6, these boards bein used to form a backing for the mold and also to produce airspaces within the wall when they are finally removed. They are tacked or otherwise fixed in place temporarily between the studding. Into the mold or form thus produced the cement or cementitious filling 11 is then poured and tamped, so that it fills the spaces in the lathing and also the design in the faceplate 9. After the filling hardens the faceplate 9 is removed and also the back boards 10. Then the interior lathing 12 and plaster 13 is applied to finish the wall. This leaves the wooden studding 6 completely embedded in and covered by fireproof material.

The expanded metal or woven wire 7 forms a tie which holds the parts of the wall together and prevents uneven settling and separation or cracking incident thereto. The removal of the boards 10 leaves a vertical air-space 14, with its known advantages. By making the face-plate of large size a large part of the wall can be molded at each operation, and the wall is built up by successive courses or parts, and the face-plate and backing-boards being moved as the Work progresses. I

The method of construction describedis much cheaper and easier than molding blocks and laying the same. A ceiling can be molded in the same manner by attaching the face-plate under the joists and pouring in the cement or concrete at the top, the woven wire then serving the usual purpose of supporting the weight of the cementlfilling,

which in such case can be made lighter than .the space between the face-plate, back boards and studding with cementitious material, and removing the face-plate and back boards after said material sets.
